They stick to their no dragging streak

Like seriously this drama is so fast pacing they don't get stuck in one arc they always get it done in 1 or 2 episodes hopefully they stick with it Also this is one of those c drama where I wish there were more episodes to see everyday im gonna miss when it stops airing ????

A real master

Two masters. Which master is more worthy? What lessons of honor and friendship need to be learned to avoid losing one's sanity? Who is the hero? Who is the enemy? All conflicts can be resolved and all illnesses of the soul can be cured. The bonds between master and disciple cannot be broken.
And what's the point of this elder having his white hair turned black. What does this mean?
